JULIAN KENNEDY, OF BRADDOOK, PENNSYLVANIA.

CINDER-CAR FOR BLAST-FURNACES.

SPECIFICATION forming part of Letters Patent No. 266,480, dated October24, 1882.

Application filed Jun- 3, 1582. (No model.)

To all whom tt may concern:

Be it known that I, JULIAN KENNEDY, of Braddock, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Cinder-(Jars for Blast-Furnaces; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, in whichFigure 1 is a side elevation of my improved cinder-car. Fig. 2 is a planof the car-body. Fig. 3 is an enlarged transverse vertical section ofFig. 2. Fig. 4 shows a front elevation and end view of the T- headedcenter post. Fig. 5 shows respectively a bottom view and longitudinalvertical section of the bolster, and Fig. 6 a transverse section of thesame. Figs. 7 and S are respectively a vertical section and horizontalsection of a modified car-body.

This invention relates to that branch of blast-furnace equipment knowncommonly as a cinder-c'ar -a car usuallyv composed of a cast-iron boxset on a truck. The usual prac tice isvto tap the cinder into this box,then move it into the open air, and after it has cooled sufficiently tosolidify the cinder or slag remove the latter by dumping the box or bodyor by lilting out the cake ot' cinder by means of a hook inserted in themass while liquid and anchored therein by solidification of the sla Thispractice demands a small car which can be handled in the describedmanner, and renders difficult the subsequent disposition of the largecakes. Besides, in the modern practice of the blast-furnace the fiow ofcinder is sometimes so great that it cannot be handled by these smallcars.

The object of this invention is to provide a form of car which permitsof construction on a large scale while facilitating the disposal of itscontents.

To these and other ends my invention consists in constructing thecar-bod y with arched sides and bottom of plate-iron and lining the samewith fire-brick, whereby the lining is prevented from floating out ofposition when the car is full of cinder; further, in providing the carwith a large swinging door at its lowest level; and, further, in theconstruction and arrangement of parts, substantially as hereinafterdescribed and claimed.

I form a shell of plate-iron, consisting of the sides a and bottom I).The bottom I) has a double curvature, sweeping in one curve from end toend and another curve from side to side. The sides a incline inwardly toa slight extent from top to bottom, and are curved from end to end. Allthese curvatures are arranged with the concavity toward the interior ofthe car. Thus constructed, a lining, c, of fire-brick is set on thebottom and built along the sides, and the arched form of both bottom andsides prevents the bricks c from becoming detached and floating out whenthe car is tilled with the molten cinder. The side linings are held inplace by the angle-iron (I, which is set on around the upper edge ofthecar. The bottom is re-enforced by the T-iron stift'e11ing-ribs c.Having in view the preservation of the lining by giving it the formof-an arch, it is obvious that such form may be produced in a variety ofways, all within the scope of this invention. As an illustration, thesides a may take the form of a cylinder, as shown at Figs. 7 and S, andthe bottom arched in either double or single curvature. This form may beadvantageously used on broad-gage tracks.

To the sides a of the car-body I. rivet the channel-bars], which conformin curvature and are as much longer than the body as will permit of thebolting between them of the bolsters g. These are of cast-iron, and arefixed firmly in position. Near each end of the bolster g, I cast the webh, open on the under edge to form a bearing for the Thead t of thecenter post, J, which allows a free vertical play to either end of thecar without straining any of its members. The trucks are each formedwith a socket, it, to receive the center post, J, thereby allowing thehorizontal sway required in going around very sharp curves. The car isthus arranged to accommodate itself to all curvatures and inequalitiesof track.

By the foregoing construction I can build a car capable of taking ten ortwelve tons of slag at one time, but as such a mass cannot beconveniently dumped or emptied by the crane, I construct it with a largedoor, M, at the lowest point on one side, as shown. \Vhen the car hasarrived at the cinder-dump the door M is opened and the contents of thecar flows out rapidly, since the mass of cinder is so great I that itremains fluid for a long period after its discharge from the furnace.

I claim as my invention 1. A cinder-car body composed of plate-ironshell and lining of refractory blocks, the sides and bottom being archedthroughout, substantially as described.

2. A cinder-car body having its sides composed of plate-iron lined withrefractory blocks, both sides and lining being arched, substantially asdescribed.

3; A cinder-car body having its bottom composed of plate-iron lined withrefractory blocks, both bottom and lining being arched, substantially asdescribed.

4. A car-body having the inclined sides a arched, as described,throughout, in combination with the curved channel-barsfand suitablebolsters, substantially as set forth.

5. In a car, the combination of the bolsters angle-irons d to retain thelining, substantially as described.

7. A cinder-car having the plate-iron sides an d continuously-archedrefractory lining,with an opening or openings in said sides and a doortherefor, substantially as described, whereby the fluid cinder may bequickly discharged.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JULIAN KENNEDY.
